You are not limited to just peacocks. Try your hand at sketching out different motifs with the zipper teeth. Many designs can be adapted to becoming pendants if brooches are not your thing. Or consider getting the brooch/pendant combination finding so you don't have to make up your mind!

Pearl, what a delightful tutorial. The brooch is so precious and I could hardly believe how jewel like the zipper teeth look. The metal zipper went from being just a utilitarian object to becoming a tiny treasure.
